I CAP non LUBRICANT-CUPS.

Specification of Letters Patent.

Serial No. 448,470.

To all whom it mag concern:

Be it known that I, GEORGE W. BOWEN, of Auburn, in the county of. Cayuga and State of New York,-'have invented a certain new and useful Cap for Lubricant-Cups, of whichthe following is a specification.

My invention hasfor its object the produc tion of-a cap for a lubricant cup, which is particularly simple in construction and ecolike characters designate corresponding parts in all the views.

Figure 1 is an elevation of a lubricant cup comprising a cap embodyingmy invention.

Fig. '2. is a vertical sectional view thereof.

- Fig. 3 is a top plan, partly broken away, of

my cap. Fig. 4- is an isometric view. of said ca lhe base 1 of the lubricant cup illustrated ject from .the adjacent art of the cap. As

best seen in Fig. 3, sai hand-engagin por-v tion consists of a, pluralityof eripJhera pro-' j ections or corrugations 3, pre era ly formed hollow, spaced equal distances apart, and extending from substantially the junction of the top 4 and the peripheral wall 5 of the cap 2, said projections 3 being formed b y distorting and spreading portions of the sides of the cap outwardly laterall relatively to the adjacent parts of the cap, y pressureacting on the interior of the cap in a direction substantially radially relatively to the axis of the cap. Said cap may be provided withfinternal threads for securing the same to the base 1.

The cap 2 is formed from a sheet. metal shell, the peri heral projections 3 bein formed by crushing the crownof theshel and holding the major portions of the barrel thereof and the portions alternating with said projections, from contracting or spread-- ing, thereby forcing outwardly parts of the shell along barrel thereof.

As is obvious, a ca for a lubricant cup constructed as descri ed, maybe manufactured quickly, cheaply and with minimum labor.

The construction of my cap for lubricant on s will now-be readily understood upon re erence to the foregoing description and the accompanying drawing.

What I-claim, is

1. As a newarticle of manufacture, a cap.
